Pro installation vs. self-installation

When you’re signing up for your AT&T Internet service, you’ll be given a choice: you can either have a professional set up your service for you, or you can order a self-install kit and handle things yourself. There are pros and cons to each method, so let’s take a look.

Advantages and disadvantages

Pro install


  • Installation tech does all the work and handles any issues that arise
  • No technical knowledge required


  • Installation fee
  • Appointment times that may require you to adjust your schedule



  • No installation window—can be done whenever
  • No extra fees


  • Troubleshoot any issues yourself or call the support line
  • Need some basic technical knowledge

Deciding between the two is fairly easy. Just ask yourself this: if something comes up, are you okay troubleshooting it yourself? It’s not a complicated process, but occasionally things can go wrong. And with no tech there to diagnose the issue, you’ll have to either handle it yourself or have someone come out to fix it.

AT&T customer support

For the do-it-yourself folks, there’s a handy AT&T support site for when you run into trouble. You can also call 1-800-288-2020 any time for AT&T customer service.

Self-install AT&T Internet

If you’ve decided to self-install your internet service, the first step is ordering an installation kit. You can do this when ordering your service, and AT&T will ship the kit to your home. Before you go any further, inspect the kit and make sure nothing is missing.

What’s in your AT&T installation kit?

The AT&T self-installation kit includes everything you need to get going:

  • AT&T Wi-Fi Gateway (this is an AT&T modem and AT&T router in one device)
  • Green data cable
  • Yellow Ethernet cable
  • Gray cable for AT&T phone service
  • Power cord
  • Detailed instructions

Self-installing your AT&T Internet service

Once you’re sure nothing’s missing, you can get started with the installation. It’s easier than you might think! Here’s how to set up your AT&T connection:

  1. Connect one end of the green data cable to the green broadband port on your gateway.
  2. Connect the other end to the AT&T Broadband jack in your wall.
  3. Connect the black power cord to the back of your gateway, and plug it into an electrical outlet.
  4. Wait for the AT&T Gateway to power up. This can take up to 10 minutes.You’ll know it’s done when the broadband and service lights are solid green.
  5. To set up AT&T home Wi-Fi access, you’ll need to log in to your computer, select the network, and enter the password found on the yellow sticker on your gateway.
  6. For Ethernet access, connect the yellow Ethernet cable to the yellow jack on the gateway and plug it into your computer.

That’s it! You should now be online with your new AT&T Internet service. If you ran into any issues, contact AT&T customer support with the information we provided above.

Activating your AT&T Internet service

Activating your service is just as simple as setting up your AT&T equipment. Once the gateway is set up, just open your web browser to begin the registration process. If registration doesn’t start automatically, you can also go to to get your service registered. (Your new router will trigger the site for registration the first time you visit.)

Why it’s good

Letting an AT&T technician install your equipment and activate your service has a couple of advantages. For one, you don’t have to worry about anything except being home at the scheduled time—the tech will handle the rest. And if something goes wrong during the installation, they can troubleshoot the problem and take care of it right then and there.

What to expect

Appointment windows are generally two hours, which means you’ll need to be home for that time. You’ll get an appointment date and time when you order your service. You can reschedule that appointment up to 48 hours beforehand using AT&T’s online order manager. Keep in mind that depending on what work needs to be done, appointments can take up to four hours (if you need lines installed, for example).

How to prepare

AT&T offers a handy checklist for preparing for your appointment. Here are the basics:

  • Someone over 18 needs to be present.
  • Set aside about 4 hours for the installation (this time can vary depending on what needs to be done and if anything goes wrong).
  • Move any furniture-blocking phone or computer connections before the tech gets there.
  • Have a payment method on hand that can be used for your AT&T service.

Equipment: renting vs. buying



  • Simpler tech support
  • Guaranteed compatibility
  • No additional cost—equipment is included in your package price


  • May be missing some advanced features




  • Choose equipment based on specific needs
  • Keep your equipment even if you cancel AT&T service
  • Pay no monthly fees


  • Higher price up front
  • No AT&T tech support for third-party equipment


As you’d expect, AT&T provides all the gear you need to use your internet service. The all-in-one gateway is a nice touch—no need for a separate modem and router. The best part about AT&T’s equipment, though, is that there’s no additional cost. The AT&T Gateway is included in your package price. This is a nice touch, especially since many Internet Service Providers (ISPs) charge an extra monthly fee for the necessary equipment.


If you don’t want to use AT&T’s Gateway, you have the option of supplying your own. Since AT&T provides its equipment at no charge, you can use the gateway as your modem and just add your own wireless router rather than a router and modem, saving you some money. The main reason to bring your own router is if you have a special circumstance, like a particularly large home that requires more range. That said, a mesh network might be a better option.

Our verdict:

Most people should stick to AT&T’s equipment, unless they need something with more range or advanced features.

Enjoy your AT&T service.

Whether you choose self-installation or decide to let the pros handle it, the process of setting up your AT&T Internet service is about as painless as it gets. And once it’s done, you get to enjoy the benefits of a trusted ISP with wide availability and excellent speeds.
